JTRP Technical Reports
With increase in axle loads, tire pressures and volume of truck traffic there has been an increase in the rate of which bituminous pavements are exhibiting rutting. Because resistance to rutting can be increased by the addition of crushed aggregate, a need exists for a method of determining what amount of crushed material is required and the characteristics of that crushed material to optimize performance and economy.
The Accelerated Testing Facility will be located at the INDOT Research Division Facilities in West Lafayette, Indiana. A pit within the Test Facility will allow prototype scale pavement sections to be installed. An …
